My dd is 3.4 months old and has no noticeable sleep cues. This is a typical scenario and I really don't know if she is OT or UT. Wake at 8:00am, naps for 1 hr 15 min, awake for 1 hr 20 minutes, naps for 35 minutes, and because she got such a short nap I start putting her down after 1 hr. However, sometimes she will cry as soon as I start to put on her clothes as if she knows she's going to go down for a nap and it take 20 minutes to get her to sleep and she will just all of a sudden stop crying and fall asleep on me and then I transfer to the crib. Of course, she wakes up less than 1/2 hr and is cranky. Or if I am really lucky she will sleep 40 minutes. We have a good wind down routine where I change her diaper, put on her clothes and then she sits on me.
I think it is OT but then I would think the A times are ok, plus I wouldn't think she would start crying as soon as the nap routine starts. Any ideas?
